However, when the number of windings of each split coil constituting the laminated high-voltage coil is small, the voltage generated in each split coil becomes small, so that the output voltage of the high-voltage coil naturally becomes small. For this reason,
There is a problem in that the output voltage of the high voltage coil must be increased by increasing the number of layers of the split coil to make it multilayer. As a result, there is a drawback that the time required for winding the high voltage coil increases and the outer diameter of the high voltage coil increases due to the multilayer structure of the split coils, which in turn increases the size of the flyback transformer. Further, in the case of multiple layers, there is a drawback in that the higher-order harmonic tuning is lost due to an increase in interlayer capacitance between the divided coils forming the high-voltage coil, resulting in poor regulation of the output voltage of the high-voltage coil. It was Therefore, an object of the present invention is to provide a flyback transformer that is excellent in high-order harmonic tuning and high-frequency operation, and that is small in size and capable of obtaining a large output voltage.
